ナスダック市場 : 上場企業一覧
 ナスダック市場ナスダック（NASDAQ）は3,300以上にのぼる企業が上場している世界最大の新興企業向け株式市場で、アメリカを代表するマイクロソフトやインテルなどが上場しています。
現在1日につき1.8億以上の取引が行われ、他のアメリカ内の証券取引所を上回る取引数となっていますが、時価総額がナスダックより遥かに超えるという理由で、NYSEの方が最大級の証券取引所と考えられています。 NASDAQには様々な種類の企業が上場していますが、公開基準がニューヨーク証券取引所よりも低いという点で、主にハイテク企業、高成長企業の市場として知られています。また、ナスダック（NASDAQ）とは、全米証券業協会（NASD）が運営する店頭株市場のことです。
ナスダックは、実際の「取引所」という物理的な場をもたず、コンピュータネットワークを通して売買が行われます。実際の取引は売り手と買い手が直接行うのではなく、マーケットメーカーと呼ばれる仲買人を通して行われ、マーケットメーカーの示した買値が売り気配値、売値が買い気配値となります。
ナスダックはニューヨークタイムズスクェアの一角にあり、巨大屋外テレビを使用して、24時間最新のマーケット動向を伝えています。
